SMOKE-SEPARATOR.

TMUEEMWQW To all whom it may concern Be it known that l, HEINRICH V. P.NIEL- SEN, a citizen of the United States, residing at Boston, in thecounty of Sufiolk and State of Massachusetts, have invented certain newand useful Improvements in Smoke-Separators, of which the following is aspecification.

This invention relates to smoke-separators and more particularly toapparatus for removing the carbon or soot from the volatile productionsof combustion, that is such particles as are held in suspension by thegases, and my object is to produce apparatus of this character wherebythe gases charged with such carbon or soot may be thoroughly washed toeffect the precipitation of the carbon or soot preliminary to the escapeof the gases.

A further object is to produce apparatus of this character which willoperate efliciently and which can be built and installed in connectionwith the fire box of any boiler or furnace at a comparatively smallexpense, whereby the darknes of the smoke may be abated and the smokeemitted into the open air comparatively colorless.

To these ends the invention consists in certain novel and peculiarfeatures of construction and organization as hereinafter described andclaimed; and I attain these objects by the apparatus illustrated in theaccon'ipanying drawing, in which Figure 1 is a view in perspective ofthe tank; Fig. 2 is a vertical section of the tank on the line 1 2 ofFig. 1, showing a vertical section of the chambers and pipes containedin said tank on said line 1 2.

Similar letters refer to similar parts throughout the several views.

A is an air-tight tank containing water of a desired depth; C is avertical cylindrical chamber located in said tank, said chamher beingopen at the lower end, and having a conical or dome shaped sealed top orcover D; the said chamber C is raised a suitable distance from thebottom of the tank A allowing the water in the said tank A to passfreely in or out of the said chamber C malntaining the same level in thechamber as in the tank, and also allowing the solid products thatcollect in the said chamber and settle at the lower end thereof to washout or be removed from said chamber; said chamber may be supported inany desired Specification of Letters Patent.

manner but I prefer to support it on legs H as shown in the drawing; Bis a smoke pipe or flue passing through the top of the tank A andprojecting through the conical or dome shaped sealed top or cover D itsend being submerged in the water contained therein, the other end of thesaid smoke pipeBbeing connected with a fan or blower, not shown,operated by suitable means for forcing the smoke through the pipe B intothe water in said chamber C; C is another vertical cylindrical chamberhaving a conical or dome shaped sealed top or cover D. The said chamberC is raised a suitable distance from the bottom of the tank A allowingthe water in the said tank to pass freely in or out of the said chamberC maintaining the same level in the chamber as in the tank, and alsoallowing the solid products that collect in the said chamber and settleat the lower end thereof to wash out or be removed from said chamber;said chamber 0 may be supported in any manner desired but I prefer tosupport it by means of legs H as shown in the drawing. The chambers Cand C are connected by the goose neck pipe E arranged to form a watertrap at its end which connects with the chamber C and which is ofsmaller diameter than the pipe 13, The other end of said pipe E projectsthrough the conical or dome shaped sealed top or cover D, its end beingsubmerged in the water therein. It will be ob served that the chambers Cand C are similar in construction and that the object of the chamber Cis to repeat the process of washing the smoke as performed in thechamber C.

F is a. pipe arranged to form a water trap and having its inlet of lessdiameter than the inlet of pipe E, and is provided on its upper end witha cup G adapted to hold sponges or other porous material, said pipeallowing the gases or residue of the smoke to pass from the chamber Ginto theairspace above the water in the tank A. J is an outlet pipeprovided with a water-trap 1nterposed. between the ends of said pipe, allowing the gases to escape from the said tank A.

I is a water inlet pipe for supplying the tank with water when desired Kis an outlet pipe for discharging or drawing out the water from the tankwhen desired.

L is a man-hole cover the dotted line representing the opening in thewall of the tank after the cover is removed.

In operation the fan or blower forces the smoke through the pipe B intothe water in the chamber C the carbon or soot being retained in thewater the residue of the smoke rising to the air-space in the upper endof the said chamber C and being retarded by the watentrap in the pipe Eis compressed until the pressure is suflicient to overcome theresistance of the water-trap whereupon it passes through the pipe E intothe water in the chamber C where the same process is repeated and theresidue of the smoke passes through the pipe F into the air-space abovethe water in the tank A, the gases or residue of the smoke being againcompressed until the pressure overcomes the resistance of the water-trapin the pipe J, -whereupon the gases or residue of the smoke escape intothe open air separated from the carbon or soot and comparativelycolorless.

' It will be seen from the drawing that the main feature of theapparatus is the arrangement of suitable chambers containing water andsuitable connecting and discharging pipes provided with water traps,through which the gases or residue of the smoke pass, thereby receivingsuccessive washings. It will be apparent from the drawings that theoutlet to each bath is constricted in comparison to its inlet. This hasbeen found to be practically essential to an eifective cleansing of thegases.

I also wish it to be understood that I do not desire to be limited totwo chambers as shown and described, as under some circumstances onechamber may effect the desired result, and under other circumstancesmore than two chambers may be necessary to effect the desired result, itbeing obvious that the number of chambers necessary in the tank willdepend on the size of the fire box of the boiler or furnace producingthe smoke.

I am aware that prior to my invention smoke separators have been madeconsisting of a tank containing water, and a fan or blower for forcingsmoke into water, thereby washing it. I therefore do not claim such acombination broadly; but

I claim:

A smoke-separator, comprising a. closed chamber, receptacles independentof and disposed within said chamber, and each having an open bottom, aclosed top, and legs supporting it above the bottom of said chamber,pipes connecting the several receptacles and each extending from a pointnear the water level in one receptacle to a point below the water levelin the next receptacle, and formed, intermediate its ends, with awater-trap, an inlet-pipe for the gases and smoke communicating with thefirst chamber, a pipe leading from the last receptacle in the series andextending upward entirely within said chamber, and formed, intermediateits ends, with a water-trap, and, at its top, with a cup adapted tocontain a sponge or the like, and an outlet-pipe for the gasescommunicating with said chamber and formed, intermediate its ends, witha watertra HEINRICH V.
